It is responsible for executing computational tasks. It is a part of a CPU that receives instructions and performs actions and do the calculations. Core in a Processor is a set of instructions that allows a software program to perform a specific task. Core i5 is a mid-range processor developed and manufactured by Intel.
It is dual-core or quad-core processors. You can use it on both desktop and laptop computers. If you are playing solitaire, then you will not see much between Core i3 and Core i5 processors.
However, If you are editing multiple files in Adobe Photoshop, you can see that Core i5 performs the same task faster compared to old generation processors. Core i7 is a family of high-end performance x86 bit processors developed by Intel. It is designed for high-end desktops and laptops. Core i5 microprocessors are positioned between the high-end performance core i7 and low-end performance core i5.
Core i5 is mid-range performance processors with performance higher than those offered by the core i7. Westmere microarchitecture, the Arrandale based i5 processors are dual-core processors. These processors had the FSB replaced with direct media interface 1. These processors use socket g1. Core i5 2 nd generation core i5 processors were based on the sandy bridge. It provides higher performance at higher power efficiency. Core I5 3 rd generation of Core i5 processors, based on 22 nm processors for desktop and server.
It was introduced in This is first microprocessors to use tri-gate transistors for their product. Core I5 4 th generation of Core i5 is based on a 22nm process for mobile and desktop. Core I5 5 th generation of Core i5 is based on a 14nm process for mobile and desktop.
Intel introduced the desktop Skylake mid-range processors in All desktop models utilize the LGA socket which is used for most of the skyline desktop lineup. The 7 th generation of Core i5 was introduced in early , are manufactured on Intel was improved 14nm process which allowed higher clock speed at similar voltage.
The 8 th generation of core i5 was introduced in We're currently starting to see Devil's Canyon chips, a refresh of last year's Haswell. Before that we had Ivy Bridge and Sandy Bridge. Generally speaking a Core i3, i5 or i7 that has a newer architecture is faster than the older-architecture processor that it replaces. You can tell the architecture by the model number, Devil's Canyon and Haswell start with 4; Ivy Bridge with a 3; and Sandy Bridge with a 2. The most important thing about different architectures is making sure that you have a motherboard that supports the type of processor you're interested in.
Processors, regardless of whether they're a Core i3, i5 and i7, based on the same architecture are fundamentally the same inside. The differences in performance come from which features are enabled or disabled, the clock speed and how many cores each one has. The feature table above shows you how the most popular processors line-up in terms of features.
Note that there are exceptions see below , but you're mostly unlikely to encounter these odd models when buying a new CPU. Also, mobile processors are completely different again, so we're focussing on desktop models here only.
What's important is what these different features mean, which we'll explain. A core can be thought of as in individual processor. A dual-core processor, therefore has two internal processors, a quad-core model has four. More cores are useful for multi-tasking; for example, you can run two applications at the same time, each one having access to its own dedicated processor.
More cores are also useful for multi-threaded applications, such as video editing. With these types of applications they can use multiple cores to improve performance.
Single-threaded applications can only use a single core leaving any others idle. Some Core i7 Extreme processors have six or eight cores. Generally speaking, we find that most applications can't take full advantage of six or eight cores, so the performance boost from extra cores isn't as great.
